Link one character to another

Hi, could anyone help me please?
I need to link one character to another. For example when I hit a character he become linked to my character hand bone. Attach to component do the job but the problem is child character doesn’t fully linked to my character (moving is fine but doesn’t response to the jump).
Any ideas of how to do that?
Thank you!

I guess you need to disable the Charakter movement component of the attached character
